SPRING-SEAT.

SPECIFICATION forming part of Letters Patent No. 783,489, dated February28, 1905. Application filed January 4, 1904- Serial No. 187,607.

To all whom it may concern.-

Be it known that I, JOHN WERNER, a citi zen of the United States,residing at the city of Dubuque, in the county of Dubuque and State ofIowa, have invented new and useful Improvements in Spring-Seats, ofwhich the following is a specification.

My invention relates to spring-seats for wagons, with special referenceto those used on lumber or heavy wagons; and one of the objects is toprovide a seat which shall be exceedingly elastic, cheaply constructed,strong and serviceable, and which can be readily attached to anddetached from a wagon-box and adjusted to wagon-boxes of differentwidths.

A further object is to provide means for preventing the seat frombecoming disengaged from the wagon-box, caused by the attendant jar orotherwise connected with this class of wagons, and to quickly andsecurely lock the seat on the box.

It consists of a seat to each end of which is attached one part of adivided spring. The other part of the spring is attached to theWagonbox; and it also consists in a lock for locking the seat on thewagon-box.

The manner in which the objects herein sought are accomplished is fullyset out in the following specification when taken with the drawingsaccompanying the same and forming a part hereof.

Figure 1 is a perspective view of the seat in position and locked on thewagon-box. Fig. 2 is a side view showing the seat locked to thewagon-box. Fig. 3 is aperspective view of a portion of one side of awagon-box and ahook and locking device unlocked. Fig. 4 is a perspectiveview of one of the springs removed and showing part of the means for adjustabl y attaching the spring to the seat. Fig. 5 is a side view of thespring removed. Fig. 6 is a perspective view of one part of one of thelooking devices. Fig. 7 shows another part of the locking devices. Fig.8 is a view of the under side of the seat and one spring, showing meansfor the adjustable attachment of the spring to the seat.

Like letters of reference denote corresponding parts in each of thedrawings.

Referring to the drawings, A. designates the seat; B, the back; 1), thebase, and E the stays. It is'not essential that there be a back to theseat, but simply a base 1).

The spring G- consists of a plate of spring material partially dividedlongitudinally along in its center at H, and at the ends of the divisionsmall circular openings .1 are also formed. After the plate is thussplit one part, K, is bent downward, and the other half, M, is bentupward, forming practically two springs K and M, united together andadapted to operate in opposite directions and in parallel planes.

It will be observed that the bends in the parts M and K of the spring Grdo not commence at the openings 1, but a shortspace O nearer the center,and in that space the two parts M and K remain in the same horizontalplane. By means of this construction there is given greater elasticityto the springs or parts M and K.

For the purpose of better staying and strengthening the spring G theends N of the spring may be bent or curved downward at it or the endsbent over and clasped around a pin L, as shown at one end in Fig. 5. Thepart M of the spring thus formed is attached to the under side of thebase 1) of the seat. For a convenient mode of attaching the spring orpart M to the seat there is provided a tenon Lon one side of the spring,and on the bottom of the seat is a loop or socketf', in which the tenonbengages and adjustably secures the seat to the spring. It will be seenby this mode of construction the same seat and springs can be adapted towagon-boxes varying in width and size. The other part, K, of the springis provided with hooks, presently to be described, by which said part isadapted to be removably attached to the wagon-box.

For the purpose of readily and conveniently attaching the springs to anddetaching them from the wagon-box there is secured to the part K hooksor loops P, which project upward and are bent to conform to the shape ofthe upper edge of the wagon-box and extend down a short space on theopposite side of the box. These loops 1 are provided on their loweredges with catches R for the purpose presently to appear. Against theouter side of the box S and directly beneath each loop P is fastened aplate 1, preferably of spring metal, in which is formed a spring-tongueV, provided with a projection d and loops or hinges a, with a rod gpassing through the hinge e. To this rod 9 is also hinged a lockplateconsisting of a thin strip of metal provided with loops Z, through whichthe rod passes, to hinge the plate IV to the plate T. The plate 7extends down at i to a plane parallel with the loops in, and theprojection (Z of the tongue V projects up betweenthe loops 7c. By thismode of construction it will be seen that the spring tongue will pressagainst the end i of the plate IV and hold it in engagement with thecatches R on the loops P and in this manner lock the two together, andwhen unlocked, as shown in Fig. 3, will press against the back side of'11 and hold the plate \V open.

The manner of using my device is substantially as follows: The width ofthe wagon-box is first determined, and then the tenons b of the springsare inserted in the loops f and adjusted to the width of the wagon-box.The loops P are brought into engagement with the upper edge of thewagon-box and the plate IV brought up into engagement with the catches Rof the loops P and are held in such engagement by the spring-tongue Vpressing against the plate In this manner the seat is securely locked tothe wagon-box.

It is manifest that different details of construction may be employedwithout departing from the spirit of my invention.

Having now described my invention, what I claim is 1. In a device of thecharacter described, a seat, a spring for each end of the seat eachspring consisting of a plate partially divided and the two parts set tooperate in parallel planes, means for attaching one part of the springsto the seat, means secured to the other part of the springs forattaching them to the wagon, and a lock for locking them on the wagon.

2. In a device of the character described, the combination of a seat, aspring for each end of the seat each spring consisting of aplate ofelastic material partially divided longitudinally and the parts set toact in opposite directions and in parallel planes, means consisting of aloop secured to each end of the seat,

a tenon secured to one part of each spring and adapted to ad justablyengage the loop on the seat, and means secured to the other part of thespring for removably attaching the same to the wagon.

3. In a device of the character described, a seat, a spring at each endof the seat each spring formed of a strip of elastic material partiallydivided longitudinally and forming a double spring and set to act inparallel planes, means for attaching one of the parts to the seat, ahook attached to the other part and adapted to removably engage theupper edge of the wagon-box, and a lock engaging the hooks for lockingthe seat upon the wagonbox.

4. In a device of the character described, a wagon-seat, a spring ateach end of the seat each spring consisting of a strip of elasticmaterial partially divided longitudinally and bent to form two springsadapted to act in opposite directions and in parallel planes, means forattaching one part to the seat, a hook secured to the other part of thespring and adapted to engage the wagon-box, projections on said hook, alock for locking the seat upon the wagon consisting of a plate securedto the side of the box, a hook-plate hinged to said.

plate on the box and adapted to engage the catches on the hooks andsecure the hooks on the wagon-box.

5. In a device of the character described, a spring-seat for wagonsconsisting of a seat, a spring for each end of the seat formed of asheet-metal plate partially divided longitudinally and the parts adaptedto operate in parallel planes, means for staying the springs by curvingtheir ends, means for adj ustably attaching the seat to the springs, ahook secured to one part of each of the springs and provided withprojections upon the ends of the hooks, and means attached to the sidesof the wagon-box and engaging the projections on the hooks for lockingthe seat on the wagonbox. v

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN WERNER.
